Defining the Mandate
The Golden Thread has become one of the most overused terms in the construction industry since the Grenfell tragedy. Yet for all the marketing noise, its legal definition remains precise and demanding. It is not just a software feature. It is a statutory requirement introduced by the Building Safety Act 2022. It mandates an unbroken and digital chain of custody for building information.
This chain must stretch freely from the initial design phase through to construction and into decades of occupation. For Accountable Persons (APs), this means the era of “filing and forgetting” is over. Every decision maintaining the safety of a Higher-Risk Building (HRB) must be recorded. It must be timestamped. It must be perpetually accessible.
The Fragmentation Problem
The reality on the ground is far from this ideal. Currently, building data lives in silos. Fire engineers use one proprietary system. Structural surveyors use another. Remedial contractors might use a third or even rely on paper. When a regulator asks for a cohesive safety case, the AP is left scrambling to merge incompatible PDFs and spreadsheets.
This fragmentation creates a “Black Box” of liability. When an incident occurs, the forensic audit trail is broken by these gaps between systems. A safety case based on fragmented data is not a safety case. It is a liability. The Building Safety Regulator has made it clear that ignorance due to poor data management is not a defence.
“A safety case based on fragmented data is not a safety case, it is a liability.”

The CoreThread Solution: Unification
CoreThread acts as the unification layer. We reject the monolithic “one database for all” approach which often fails due to complexity. Instead, we act as a sovereign hub that ingests data from disparate sources into a single and verified ledger.
We create a Golden Thread that is defined by three core attributes. First is Immutability. Once a record is written to the CoreThread ledger, it cannot be altered or deleted. It allows for corrections but the original error remains visible in the audit trail. This prevents “pencil whipping” or the retroactive alteration of safety records.
Second is Interoperability. Data is not locked into CoreThread. It can be exported in open standards such as COBie to ensure long-term accessibility even if software vendors change. Third is Verification. Every entry is tied to a specific user and timestamp via the Digital Handshake.
The Digital Handshake
True reliability comes from knowing exactly who did what and when. The Digital Handshake is our proprietary method for validating contractor presence and action. When Dave the contractor arrives at a site, the app performs a passive handshake with the building’s geofence.
It timestamps his arrival without manual input. As he works, Mimir AI validates his inputs in real-time. If he scans a fire door NFC tag, Mimir checks the scan against the expected asset ID. If he logs a remedial fix, Mimir requests photo evidence and analyses it for compliance before the record is sealed.
This creates a forensic timeline that protects both the landlord and the diligent contractor. It proves that work was done correctly and on time. It eliminates the ambiguity that often leads to payment disputes or liability claims.
From Static to Living
The ultimate goal is to move the industry from static reports to a living safety case. A PDF safety case is obsolete the moment it is printed. A Golden Thread is alive. It updates with every maintenance visit. It reacts to sensor data. It evolves with the building.
As we move forward into this new regulatory era, the Golden Thread will become the primary asset of any building. It will determine insurance premiums. It will dictate resale value. It will define safety. CoreThread ensures that your Golden Thread is spun from the strongest possible material.
